'Teen Mom' Catelynn Lowell pregnant again

Another “Teen Mom” star is expecting her second baby. Catelynn Lowell, who memorably gave her child up for adoption as MTV reality cameras chronicled her journey, is pregnant again.

Lowell, 21, took to Twitter to reveal she and longtime boyfriend Tyler Baltierra, who fathered her first child too, were expecting. The pair first appeared on MTV’s “16 and Pregnant” and then on several seasons of the spinoff series “Teen Mom.”
